Y

The Atank I4 is provided with a connection 2| to which conduit I1 is suitably connected, the other end of conduit I1 being connected into the lower iiuid outlet hose connection 23 preferably arranged between the vehicle cooling radiator 24 and the water pump 26 of the internal combustion engine or prime mover 25 as at 28. The conduits I6 and I1 may be reversed whereby the heated fluid may flow into the lower tank I4 and out of upper tank I2 and conduit I1 without departing from the spirit of the invention.

As a means for securing the heater unit I0 to the dash 3U or other suitable support, Ihave provided a plurality of brackets or supports 32 preferably formed of sheet metal which may be suitably secured adjacent the conduit connections I9 and 2| by means such, for example, as screws 3 I, and to the dash or support 30 by means such as bolts 33. The brackets 32 also preferably provide supporting means for a motor 4U actuating a fan 35 or air circulating means which is preferably positioned adjacent the rear of the radiator core I'I by' means of a plate or support 36 which embraces the bearing extension member 38 of motor 4|). An element 31 is removably secured to support 36 by means such as screws 39 to retain the motor in position and by manipulating screws 39 the motor extension 38 may bev adjusted longitudinally relative to the brackets or elements 36 and 31. A bushing 4I of rubber or other suitable vibration damping material is preferably inter posed between bearing extension 38 and brackets 36 and 31 to absorb vibrations. In the form of my invention as illustrated in Figures 1 and 3, the motor 40 has been illustrated as an air motor having a connection by means of the tube 42 to the intake manifold 43 of the prime mover of the vehicle. A second conduit 44 connects the air motor 40 to a control means 46 suitably mounted within reach of the vehicle operator, which control means is in turn connected by conduit or itube 41 to the atmosphere, in the embodiment shown to the engine compartment.

The motor is of a type such that when the prime mover of the vehicle is running, the vacuum existing within the intake manifold-of such prime mover extracts-or withdraws air from the interior of theimotor casing 40. 'Ihe tube 44 leading from' the :control means to the motor chamber terminates in ajet or nozzle 45 whichv is`suitably positioned'withv respect 'to ithe blades f of the motor rotor notf shown, arranged withlin the casingA 40; so fthatUthe ,inru'shing air lcaused bythe withdrawalfof the airfrom the motorl casing or vacuumfsetsup a rotation of the motor rotor.

- 'dlrectsthefwarmed oriheated air into the vej u whicle interior. 'Ihis form oi! the invention is pro- .vided 'with a shroud 52 partiallyenclosing the am 35,illustrated in detaill inA Figures 3 and 4. The shroud: comprises a housing 53 provided with ears 54 having-openings therein to receive studs orIgseifevirrty 66 which 'are' threaded into'suitable 'openingsinjtheashell`v 50 to xedly secure the platanes lSilvrelative.tothe core II.-v The I core structure II.

sides of the core are provided with enclosures in the form of removable plates 51 provided with raised portions 58 to accommodate the studs 55. Plates 51 are positioned adjacent the sides of the core II by means such as areprovided in the anged portion 59 of back plate 53 which clamp or bind the plates 51 in position, the plates 51 serving as a locating or positioning means for the front shell 50. Means such as the elements 46 of rubber or other suitable material, may be provided between the core II and portions of the shell 50 to absorb vibrations.

It should be noted that in this form of the invention a plurality of fins 49 are positioned angularly with respect to a horizontal plane to direct the heated air downwardly. Vertically positioned water tubes 5I of the core II are arranged angularly with respect to each other and to a vertical longitudinal plane of the heater so that air is directed more particularly to one side of the heater unit.

A further form of the invention has been illustrated in Figures 5 to 9, inclusive, in which the core II of the heater unit is provided with a forward faceplate 59 which is formed with a :dxed deflector portion 60 for confining the circulation of air and directing the air downwardly and into the interior of the vehicle. In this form of the invention the shroud or means for directing air through the core comprises a back plate 6I having a substantially circular opening adaptedA to accommodate the air circulating fan (not shown). This plate 6I is provided with ears 65 having openings therein to receive studs 63 which are" threaded into suitable openings in the face plate 59 to secure vthe face plate and back plate 6I in xed relation with respect to the core. An enclosure is provided for the sides of the core comprising plates 62 which are preferably secured to the top and bottom tanks 61 and 68 as by soldering at 6 4 and if desirable may also be secured to the side edges of the ns 49. To prevent vibrations and thus noises, it has been found desirable to provide an element such as a rubber or other non-metallic strip 66 between portions of the core II and the face plate 59.

It should be noted that in this form of the invention a plurality of ns 56 are' arranged at an 'angle with respect to a horizontal plane for vthe purpose of directing heated air downwardly.

As particularly illustrated in Figure 8, the vertically positioned water tubes 69 of the core II are angularly arranged with respect to a vertical longitudinal plane'of the heater so that the air on passing the line of `water tube 69' will Vbe deected in a directionV of the plane of the tubes so asto effect an indirect heat towards the drivers or operators position of the vehicle. In this form of the invention a structure is provided which' is easily assembled and the number of parts reduced to a In the embodiment illustratedin Figures 10 to 14,A` inclusive, I, have provided a shroud construction-13 capable of being supported by the tanks 1I 'and 12 arranged above and below the In this embodiment, it will be noted thatI have provided a shroud 13 completely enclosing the sides of the core, an opening 14 being provided in the rear thereof to accommodate a fan k15 and to provide an air intake opening. .Each of thetanks 1I and 1271s provided with aconduit connection 11, an opening 16 being provided in the shroud 13 to permit the connections to extend therethrough. The tanks are reinforced at thev water'inlet and outlet connectons by means of angular brackets 10 welded or otherwise secured to the tanks.

In order that the shroud 'I3 may be secured in position adjacent the core, I have provided a plurality of studs 80 having flattened portions welded or otherwise secured to the tanks 1| and 12 as at 16 for securing the shroud thereto. A plurality of brackets or securing members 82 are secured as by welding to the tanks 1| and 12 to which is removably secured the front plate 8| having a deector portion 84 which deflector directs the circulation of air into the interior of the vehicle. The front plate 8| is provided with a plurality of screw threaded openings to accommodate screws 85 for connecting the plate to the brackets 82. Water inlet and outlet connections 11 which are preferably metal pipes,-

one of which suitably supports one end of an adjustable bracket 81 formed in two halves held together by screws 83 which in turn supports a motor 88' for driving the fan 15. The other end of bracket 81 is supported by a bracket or support 88 a portion of which surrounds the connection 11 and being screw threaded,is adapted to be secured in an opening in the dash by means such as the nuts 86. The Support 88 is preferably of 'sheet metal suitably formed to provide the projection 19 adapted to receive screws 83. In this embodiment I have illustrated an electric motor 88 for circulating the air, but it is to be understood that any other suitable type of motor may be utilized. The shroud 13 extends forwardly to provide a suitable positioning or locating means for the front plate 8|, portions 89 of which are cut out to accommodate brackets 82. The ns 56 are inclined downwardly for the purpose Y as hereinbefore stated of directing the heated air downwardly as it leaves the heating unit. Thus, I have provided a heating unit wherein the shroud and deflector arrangement is capable of being easily assembled and which is very effective to direct the flow or circulation of air through 'the radiator core II and into the vehicle interior.

The modified form of my invention illustrated -in Figures to 18, inclusive, is inclusive of a radiator core 90 having downwardly inclined vanes or ns 9| adjacent the front portion of which is positioned a shell or front plate 92 which is provided with a plurality of movable deflector units 93 pivoted to the front plate as at 94 capable of being pivotally adjusted about a vertical axis relative to the casing 92 to direct or control the circulation of air created by a fan 95. vThe core 90 is provided with upper and lower tanks 96 and 91 respectively, which in turn have inlet and outlet pipes 98 and 99 extending through the vehicle dash |00. The outlet pipe 99 is directly supported by the dash |00 by means of the nuts IDI and |02 having threaded engagement with the pipe. A bracket or support |04 is provided adjacent the conduit 98 which is secured to the tank 96 by means of screws |05. The other end of the bracket is provided with a threaded sleeve |01 which surrounds but does not contact the inlet pipe, this sleeve projects through an opening in" the dash and is adapted to be secured thereto by means of nuts |08. Preferably interposed between the sleeve |01 and the wall of the pipe 98 is a bushing I I3 of sound deading material to prevent metallic contact of these parts. The end of the threaded sleeve |01 is suitably swaged or otherwise secured as at |06 to a projection |I0 of the bracket |04. As illustrated in detail in Figure I8, the bracket |04 suitably supports a second bracket member adapted to support motor I2, which, in the em bodiment disclosed, is an electric motor for driving the fan 95. The bracket is suitably connected at its other end ||4 to outlet pipe 99, a

second bracket |09 being secured to the bracket by means of screws ||1 to retain the fan motor in position and to clamp bracket securely to the pipe 99. To prevent metallic contact between portions of the core 90 and shell 92 a rubber or other suitable non-metallic cushion member may be provided as at |03. It is to be noted as shown in Figs. 2 and 3 the rubber or non-metallic cushion member may if desired extend substantially around the inner periphery of the front plate adjacent the forward portion of the radiator unit.

I have provided a shroud ||5 adjacent the rear portion of core 90 to enclose the rear portion and sides thereof, and direct air through the core, an opening ||6 being provided to accommodate the fan 95. In this form of the invention, it will be noted that the conduit pipe 99 and bracket 04 serve as a support for the heater unit and the fan and motor, the bracket |04 serving to relieve the strain caused by the weight of the heater from being transmitted to the water pipe 98 thus providing a rigid and substantial construction. By this construction, less strain due to motor and road vibration is present, and the danger of damaging the water connections is greatly lessened, while at the same time, the supporting structure is effective to provide a very substantial supporting means easily adjustable relative to the dash and permits of easy installation in the motor vehicle. As a means4 of supporting the front shell 92 relative to the core 90, I have provided a Z-shaped bracket 8 secured to the tank 96 by means of the screws |05 and to the shell 92 by means of screw II9. Screws |05 also serve to secure the shroud I I5 adjacent the rearward portion of the core 90 and thus it will be noted that a very eicient and easily assembled structure unit has been provided.

In the modified form of my invention illustrated in Figures 19 to 24 inclusive, I have provided a shell or front plate |20, the portions |22 and |23 of which completely enclose the sides of a core |25 and the' tanks |26 and |21, respectively. Adjacent the front portion of shell |20 isa plurality of relatively movable deiiector units |28 pivotally connected thereto as at |29 by means of arms or extension elements |30 preferably having pivotal connections to the deflectors as at |32. Thus, it will be noted that by manipulating the deectors |28, they may be positioned relative to the shell |20 in any number of desirable positions to direct the air forced through the unit by means such as the fan driven by a suitable source of power as, for example, an electric motor, a portion of which has been illustrated at |34.

The tanks |26 and |21 are provided with an upper pipe |36 and a lower pipe |31, respectively, which are suitably connected to the engine cooling fluid circulating system of a vehicle. Brackets or supports |39 are provided adjacent the conduits |36 and |31 which may be supported in a manner similar to that shown in Figures l5 to 18, and are connected to the tanks |26 and |21 by means such as bolts |40. Bolts |40 also DIOVde securing means for a. back plate or shroud |42 which is further secured to the rear of shell |20 by means of screws |43 which extend through openings in the shroud and have threaded engagement with projections |44 provided adjacent the side portions |22 of the front plate |20. An opening |45 is provided in shroud |42 to accommodate fan |35 and also to provide an air inlet to the core |25.

As a means to prevent lss of air between the tanks |26 and |21, portions |23 of the front shell and the shroud |42, members or grommets |46 of rubber or other suitable material have been provided. The grommets |46v are provided with openings |41 to accommodate a drain plug |49 having screw threaded engagementwith lower tank |21, and a relief valve |50 provided in the 4upper tank |26, which valve may be opened when the heating system is being filled with water to permit air to escape.

By this form of my invention, the side portions of the front shell provide a suitable enclosure for the sides of the core, while the shroud is secured thereto to enclose the rear of the core, providing a structure capable of easy assembly and a unit of high efficiency.
